SuperPINDA standard deviation
At the bottom of Testing the P.I.N.D.A. sensor-readings in Pronterface it says this about how to evaluate the standard deviation:
You want to make sure there are no significant deviations (>0.2) between the 3 measurements.
Is the ">0.2" meant to directly apply to the resulting standard deviation calculation's bare numerical result or the percentage calculation? For example when I use Google Sheets STDEV do I evaluate the resulting bare value from my 3 measurements (0.003470778011) or the % conversion (0.35%)?
RE: SuperPINDA standard deviation
Hello,
i am only a normal user , too.
I did never do this testing myself .
But if i read this help article attentively , it says nowhere "standard deviation", it says only "deviation" between the 3 interpolated measurements at each of the 49 positions
So, i would assume it means the 3 interpolated Values (got by 3 x G81-commands) at each of the 49 positions should not differ more than 0,2 at each of the 49 points.
